Product Insights
The Lightweight Merino Long-Sleeve T-Shirt by INNER SELF is a 140 GSM merino-modal blend that offers exceptional breathability and packability, being 15–40% lighter than midweight merino shirts, while retaining odor resistance for multi-day wear. It resists shrinkage 50% more than cotton, maintains its black color and smooth texture through repeated washes, and is opaque enough to wear alone. Priced at 80 CAD, it undercuts competitors like Ibex Naturalist and Bergans. The relaxed fit provides roominess in chest and shoulders, and most wearers find it non-itchy, though very sensitive skin may experience irritation.
- Care instructions
Machine wash cold on gentle, lay flat to dry; low-heat tumble drying possible but riskier.
Why this is supported
The brand's official care guide states:
To prevent shrinkage and damage, we recommend machine washing cold on a gentle cycle and laying flat to dry. Avoid hot water, bleach, and fabric softener, as these can harm merino fibers.
What is the recommended washing and drying method to avoid shrinkage or damage to the merino-modal blend?It adds that
Tumble drying on low may be possible but increases risk of shrinkage.
What is the recommended washing and drying method to avoid shrinkage or damage to the merino-modal blend?The blend's modal content makes machine washing safe:
Modal is a high-modulus fiber with wet strength. This means it maintains good strength and dimensional stability even when wet.
sino-silk.com- Shrinkage resistance
Resists shrinkage 50% more than cotton; modal's wet strength prevents wash distortion.
Why this is supported
The shirt's modal component provides significant shrinkage resistance:
Research results demonstrate that modal fabric exhibits approximately 50% greater resistance to shrinking compared to cotton.
loomandfiber.comThis performance comes from modal's high wet strength, which one source explains:
Modal is a high-modulus fiber with wet strength. This means it maintains good strength and dimensional stability even when wet.
sino-silk.comThe fiber's microstructure also prevents compression:
modal fibers have a circular cross-section. They are smooth longitudinally but with grooves. And their edges are irregularly serrated. This means a stronger inter-fiber bonding.
sino-silk.com- Appearance retention
Modal resists fading and pilling, keeping black color and smooth texture after many washes.
Why this is supported
Modal's durability ensures long-lasting appearance:
Modal is surprisingly durable despite its soft texture. The fabric resists shrinking, fading, and pilling, which means your garments will maintain their appearance and feel even after frequent washing.

Merino's odor resistance allows multiple wears between washes, extending life.
